Answer: different and subtract go in the empty spaces

The vertex and range are (-2, -3) and y >= -3 respectively

The equation is given as:

y = |x +2| - 3

The above equation is an absolute value equation

An absolute value equation is represented as:

y = a|x - h| + k

Where

Vertex = (h, k)

So, we have

Vertex = (-2, -3)

Also, we have

a = 1

Since a is positive, then the vertex is a minimum

Hence, the vertex and range are (-2, -3) and y >= -3 respectively

Based on the linear pair theorem, the value of x is: 42°.

A linear pair is a pair of two angles that are formed adjacent to each other on a straight line. These two angles, according to the linear pair theorem, have a sum of 180d degrees when their measures are added together.

From the image, we see that x° and 138° are a linear pair as they lie on a straight line.

Therefore:

x + 138 = 180 [linear pair theorem]

Subtract 138 from both sides of the equation

x + 138 - 138 = 180 - 138

x = 42°

Therefore, based on the linear pair theorem, the value of x is: 42°.

Answer:16 and 24

Step-by-step explanation:

The algebraic expression for total hours that represents the number of hours per week the theater is open is 4 x + 3 y

Number of hours the theatre is opened on Monday to Thursday = x hours.

Number of hours the theatre is opened on Friday to Sunday = y hours.

Number of hours from Monday to Thursday = 4 x hours.

Number of hours from Friday to Sunday = 3 y hours.

Total hours will be represented by the algebraic expression:

Total hours = 4 x + 3 y.

Therefore, the algebraic expression for total hours that represents the number of hours per week the theater is open is 4 x + 3 y

Step-by-step explanation:

If the expression 16t² models the distance in feet that an object falls during the first t seconds after being dropped, then the distance of the object during 0.5 second is 4 feet

Given,

The expression model of the distance in feet that an object falls during the first t second after being dropped = [tex]16t^{2}[/tex]

Time = 0.5 second

Then the distance = [tex]16(0.5)^{2}[/tex]

The coordinates of the point on the directed line segment is (-5,5)

In the given sum we are using the internal division formula which goes like:  (x,y) = (nx₁ + mx₂)/(m+n), (ny₁ + my₂)/(m+n)

with the available data we can interpret that where m = 1 , n = 4 , (x₁,y₁) = (-8,8) , (x₂,y₂) = (7,-7)

substituting the given values in the above formulae

The coordinates of the point is :

(x,y) = (4(-8) + 1(7))/(1 + 4) , (4(8) + 1(-7))/(1 + 4)

= ( -32 + 7)/5, (32 - 7)/5

= (-25/5) , (25/5)

= (-5,5)

∴ (x , y) = (-5 , 5)

The equation of the line in point-slope form, which passes through the points located at (1 , 0) and (5 , 5), is y = 5/4(x - 1).

The equation of a line can be expressed in three different forms: standard form, slope-intercept form, and point-slope form.

The standard form of an equation of a line is expressed as ax + by = c, where a and b, if all possible must be integers, are the coefficients of variable x and y, respectively, and c is a constant. Meanwhile, slope-intercept form is given by the formula y = mx + b, where m is the slope of the line and b is the y- intercept. On the other hand, given the slope m and a point on the line (x , y), we can express the equation in point-slope form, (y - y1) = m(x - x1).

Getting the slope of the two points: (1 , 0) and (5 , 5).

m = (y2 - y1)/(x2 - x1)

m = (5 - 0)/(5 - 1)

m = 5/4

Using the point slope form, plug in the values of the slope and one point to set up the equation.

(y - y1) = m(x - x1)

where m = 5/4 and (x1 , y1) = (1 , 0)

(y - 0) = 5/4(x - 1)

y = 5/4(x - 1)

Measure of angle 5 i.e. m∠5 = 50°

The measurement of angle is the degree of that angle or we can also say that the angles are always measured in degree. In geometry, the complete one revolution of four quadrants is of 360 degrees (360°) and divided into total of 360 parts where each part of this represents a degree.

As stated above there are total 360 parts in one revolution thus thus we can find value of particular angle by subtracting the angle from 360 or 180 for a straight line.

In the question,

Let given angle is ∠8.

Given, ∠8 = 50°

Now, according to vertical angle property

∠5 = ∠8

therefore, ∠5 = 50°

Thus, m∠5 = 50°

The arithmetic mean of the monthly salaries of two employees is $ 3210 . One employee earns $ 3470 per month. What is the monthly salary of the other employee.

Then $2950 is the salary of the other employee.

$2950 is the monthly salary of the other employee.

a. the given information = mean of two salaries =  3210

                                       = salary of 1st employee =3470

the unknown information = salary of 2nd employee = 2950

The arithmetic mean is the most straightforward and widely used method of calculating a mean or average. It only requires adding up a group of figures, then dividing the result by the entire amount of figures in the series. Consider the numbers 34, 44, 56, and 78 as an example. It totals 212.

The mean or arithmetic average are other names for the arithmetic mean. It is determined by adding up each number in a particular data set, then dividing the result by the overall number of items in the data set. For uniformly distributed integers, the middle number serves as the arithmetic mean (AM).
